Ultra-fast and ultra-thin balanced type electric heating machine

Abstract

The invention relates to an ultra-fast and ultra-thin balanced type electric heating machine. The ultra-fast and ultra-thin balanced type electric heating machine comprises a casing, a main heating body and an electrical control system assembly, wherein a convection channel is formed in the casing; an air inlet and an air outlet are formed in an upper end and a lower end, corresponding to the convection channel, of the casing respectively; the main heating body is a film covered heating body which is arranged on the inner side of the convection channel and electrically connected with the electrical control system assembly. According to the ultra-fast and ultra-thin balanced type electric heating machine, the temperature increase speed is high, the increased temperature is stable, heating power in each position of the film covered heating body is uniform and consistent, the heating machine is not influenced by various outside environments, and natural type up-and-down convection heat dissipation is combined, so that the fast heat transfer effect is achieved; further, the ultra-fast and ultra-thin balanced type electric heating machine is stable in structure and reliable, and unnecessary mounting cost and additional material cost are saved by means of the film covered heating body; compared with the prior art, the ultra-fast and ultra-thin balanced type electric heating machine has the advantages of simple structure, convenience in use, high working temperature increase speed, simplification in mounting, cost reduction and the like.

Description

technical field [0001] The invention relates to a household electric heating device, in particular to an extremely fast ultra-thin counterbalanced electric heater. Background technique [0002] The prior art heater is PTC (honeycomb) heating, and the fan is used to send heat from the shell to the external environment. The surface temperature rise is usually not easy to control, and the noise is large. If the noise is to be reduced, the power is not enough, or the cost of the motor will also increase. , the product assembly is difficult, it needs to be fixed with screws, and there is also a metal shelf, the cost is increased, and the quality is unstable. Usually, the wind speed and air volume of the fan must reach a certain value, and the power can guarantee the set effect. The existing household heating The fan power is more than 200 watts, which will increase the size of the fan, that is, the cost of the fan will increase, the copper wire of the motor will increase, the mot...

[0002] The prior art heater is PTC (honeycomb) heating, and the fan is used to send heat from the shell to the external environment. The surface temperature rise is usually not easy to control, and the noise is large. If the noise is to be reduced, the power is not enough, or the cost of the motor will also increase. , the product assembly is difficult, it needs to be fixed with screws, and there is also a metal shelf, the cost is increased, and the quality is unstable. Usually, the wind speed and air volume of the fan must reach a certain value, and the power can guarantee the set effect. The existing household heating The fan power is more than 200 watts, which will increase the size of the fan, that is, the cost of the fan will increase, the copper wire of the motor will increase, the motor will consume a lot of power, and waste resources. If it is enlarged, the volume and thickness cost of the entire shell will also increase. The increase in material cost will increase the manufacturing cost, and the safety hazard will also increase when the weight increases. The control performance of the motor is poor, and the speed change is difficult. In 220V mains electricity, insulation and safety protection measures are usually required to increase unnecessary burdens on consumers

[0003] In addition, the material cost of the heating belt is higher than that of the film heating element, and the assembly cost of workers is also increased (the assembly cost is not required for the film), and the heating belt often encounters the phenomenon that the main body is not attached tightly during the product assembly process, which results in the product working effect Poor, affecting product quality, the power can not meet the requirements, in the process of transportation and packaging process of the heating belt, due to collision, bending, the phenomenon of breaking the heating belt is not uncommon, resulting in damage to the heating belt or no heat, affecting quality problems
